Subject: RE: RV8-List: RE: RV-List: Fixed pitch to constant speed
Here's a tip for anyone building wing tanks for a RV-8.
A friend building an RV-10 told me about the fuel pickup tube on the RV-10. It
has a strainer attached to the pickup end of the tube. That's a real improvement
over the pickup tube in my RV-8 plans. My plans say: bend the tube and crimp
the end of the tube and then hacksaw 7 or 8 holes about half way through the
tube just above the crimp for the fuel pickup.
I ordered the RV-10 tubes from Vans and found them to be a perfect fit and a much
niftier way to go. They are nicely bent and come with the compression sleeve
and nut already mounted on the flared end of the tube. All that you have to
do is screw the nut on the fitting that passes through the inboard tank rib and
install the locking bracket.
It was a little tricky finding the RV-10 tubes in the Vans catalogue, but they
are there. I forget how much they cost. I think both for $31 or so. Well worth
it to me for this important component.
Regards to all.

Craig,
I did this conversion on my 8A about three years ago. After reviewing all the
performance data on the various CS props available, I selected the Hartzell blended
airfoil. I have an IO-360, 180 hp engine so the engine weigh is the same
as yours.
Looking back over my W&B data, I can tell you the Hartzell was 13 pounds heavier
than the Sensenich. I have two Odyssey 625 batteries mounted just aft of the
firewall. I considered moving one of them to the aft mount location but decided
to wait until after flying to see if it I had a nose heavy problem or not.
Bottom line, I did not see much difference so I left the batteries where they
are.
As I did with the Sensenich, I put a 25 pound shot bag in the baggage compartment
if I'm solo and no baggage. My W&B does not require this, but I find it helps.
I can tell you the performance difference between the Sensenich and the Hartzell
was far more dramatic than I anticipated. You will love the change. I have
a couple of hotrod Lancairs at the airpark and while they eventually pass me,
I give them a surprising run for their money.
BTW - I'm using the PCU-5000 governor and am very pleased with it. If you need
a governor control cable bracket let me know - I have a new one sitting here
I bought from Van's by mistake for the RV-10.

Do you have your battery in the back?
I have an IO-360 200 Hp / Hartzell BA CS prop (great combination) and have no issues
flying solo with full fuel or near empty and no weight in the back.
One note I have dual G3X and back up EFIS so I suspect my panel is lighter than

I have a RV8a with a IO-360 200hp which is a little heavier than your engine plus
I have constant speed prop and have been flying it since 2002. That being
said I do keep 25 lb. of lead shot in the aft baggage compartment and a few tools
which keeps the elevator pretty even or level in flight thus creating less
drag. When landing it also helps with a lot less trim. I have confess my best
landing are when I have a passenger in the rear seat and nothing in the aft

Does anyone out there know how the installed weight of a Whirlwind prop compares
to the fixed pitch Sensenich? The Whirlwind prop and spinner weigh in at
about 38# according to the folks at Whirlwind. I was hoping to find out the
weight of the Sensenich installation without pulling my prop.

I am also sending this to my friend Joe Blank at Vans in case I am missing something
and potentially putting out bad information.
Joe, don't hesitate to chime in. Subject is installing RV-10 fuel pickup tubes
(with strainers) in RV-8 tanks. My original email is at the bottom. Gail
RETRO RV-8 Fuel Pickup Tubes
It should be easy to replace the RV-8 fuel pickup tubes with RV-10 tubes (with
the strainer on the end of the tube) if the wings are not on the aircraft and
if the tanks were manufactured with the conventional fuel pickup versus the inverted
pickup system.
Degree of difficulty could be influenced by how the fuel pickup/sensor float assembly
plate was mounted on the inboard tank rib with respect to sealant and the
gasket.
I don't have the plans in front of me right now to refer to part numbers, but visualize
the inboard tank rib with the round 6 or 7 inch diameter hole containing
a cover plate with fuel pickup tube, fuel level sensor, etc. There are a number
of screws holding the cover plate in place. It should be as simple as disconnecting
the fuel plumbing, removing the cover plate and lifting out the fuel
sensor and pickup tube assembly which are attached to the cover plate. Then,
remove the fuel pickup tube locking bracket (drill out two rivets), clean the
surfaces and reassemble with the new pickup tube part, including the locking
bracket and the cover plate gasket. Don't forget to use sealant on the locking
bracket rivets. I haven't done it, but that would seem to be the way to get
it done.
If the wings are on the aircraft, it might pose more of a problem. I don't have
experience at that level yet. But, if one can get to the cover plate on the inboard
tank rib, the rest should be fairly easy.
If that is not possible it should be fairly easy to remove the tank from the wing
and proceed as above.
